• Security and privacy are essential
• The web must enable freedom of expression

• The web must enhance individuals’ control and power
• The web must be an environmentally sustainable platform
• The web is transparent
• The web is multi-browser, multi-OS and multi-device
• People should be able to render web content as they want
